Answer:
it's B
Step-by-step explanation:
i got right on my assessment and because if you look closer when X is in the negative side the line is straight but when the line increases and the x is in the positive side it's curved
when x<0 the graph is linear and when x>0 then the graph is non- linear.
What is linear and non linearity in a graph?A linear function is one that, when plotted, forms a straight line. Therefore, non-linear functions are all non-linear functions. We can discern if a function is linear or non-linear from its input/output table or equation, but graphing may be the quickest way to do it.
Something that is linear is related to a line. A line is built using all of the linear equations. A non-linear equation is one that cannot be represented by a straight line. It has a variable slope value and resembles a graphed curve.
Given:
We have the graph
From the graph we can see that when x<0 then there linearity or proportionality between x and y.
and, when x>0 then the graph is not a line it is turned out in a curve, which is not linear.
Hence, when x<0 the graph is linear and when x>0 then the graph is non- linear.

Sales personnel for Skillings Distributors submit weekly reports listing the customer contacts made during the week. A sample of 35 weekly reports showed a sample mean of 19.5 customer contacts per week. The population standard deviation was 5.2. Provide a 99% confidence interval for the population mean number of weekly customer contacts for the sales personnel.
Answer:
The answer is below
Step-by-step explanation:
Given that:
Confidence interval (C) = 99%, mean (μ) = 19.5, standard deviation (σ) = 5.2, sample size (n) = 35
α = 1 - C = 1 - 0.99 = 0.01
α/2 = 0.005
The z score of α/2 (0.005) is the same as the z score 0.495 (0.5 - 0.005) which is equal to 2.576.
The margin of error (E) is given as:
[tex]E=Z_\frac{\alpha}{2}*\frac{\sigma}{\sqrt{n} } \\\\E=2.576*\frac{5.2}{\sqrt{35} } \\\\E=2.264[/tex]
The confidence interval = (μ ± E) = (19.5 ± 2.264) = (17.236, 21.764).
The confidence interval is between 17.236 and 21.764.
A taxi charges a flat rate of $1.75, plus an additional $0.65 per mile. Erica has at most $10 to spend on the cab ride. How far can Erica travel?
Answer:
x = 12.7 or x ≈ 12
Step-by-step explanation:
1.75 + 0.65x = 10
0.65x = 10 - 1.75
0.65x = 8.25
x = 8.25 / 0.65
x = 12.7
x ≈ 12
note: we round it up to 12 and not 13, because Erica does not have enough money for 13 miles

Answer:
(H) y = 1/3x + 5
Step-by-step explanation:
When x=0, y=5, so you know G is not a possibility.
Y increases at a lower rate than x does. For example, between the first two table entries, x goes up by 6, but y goes up by 2. The only choice with a rate of change less than 1 is ...
(H) y = 1/3x + 5

Josh wants to add a model of a tree house to his model railroad layout how big should the tree be if the actual tree is 315 inches and the scale is 1:90
Answer:
3.5 inches on the scaled model
Step-by-step explanation:
So using the ratio, 1:90 I thought of two ways to solve this
1) Proportion
2) Equation
Using the proportion method
1:90=x:315
Now cross multiply
315=90x
Now solve and you’ll get 3.5
Equation is just
315/90=X?
Just solve and you’ll also get 3.5

The function g is defined by:
g(x) = x² - x - 6
so
g (-4) = (-4)² - (-4) - 6 = 16 + 4 - 6 = 14
When g(x) = 6, we have
6 = x² - x - 6
x² - x - 12 = 0
Solve for x. We factorize this easily as
(x - 4) (x + 3) = 0
which gives
x - 4 = 0 or x + 3 = 0
x = 4 or x = -3

Determine the solution to the following system of equations: x + y = -3x - y = 1
(-2,3)
(-1,-2)
(0,0)
No Solution
Answer:
( -1,-2)
Step-by-step explanation:
x + y = -3
x - y = 1
Add the two equations together to eliminate y
x + y = -3
x - y = 1
------------------
2x = -2
Divide by 2
2x/2 = -2/2
x = -1
Now find y
x+y =-3
-1 +y = -3
-1+1 +y = -3+1
y = -2
( -1,-2)

A particle starts to move from rest in a straight line with an acceleration which increases with constant time rate from 1 ft./sec^{2} to 4 ft./sec^{2} in one second. prove that the particle will move a distance of 1 ft. in this second.
The particle's acceleration a increases at a constant rate, so that its average rate of change is equal to its instantaneous rate of change, which is equal to
(4 ft/s² - 1 ft/s²) / (1 s) = 3 ft/s³
The particles starts with acceleration a (0) = 1 ft/s², so we can determine its acceleration at time t by the fundamental theorem of calculus:
a(t) = a (0) + ∫₀ᵗ (3 ft/s³) du
a(t) = 1 ft/s² + (3 ft/s³) t
It also starts from rest, so with initial velocity v (0) = 0. Integrating again gives us the velocity function,
v(t) = v (0) + ∫₀ᵗ a(u) du
v(t) = ∫₀ᵗ (1 ft/s² + (3 ft/s³) u) du
v(t) = (1 ft/s²) t + 1/2 (3 ft/s³) t ²
Taking the particle's initial position to be x (0) = 0, compute the integral again to determine the distance it travels in 1 s:
x(t) = x (0) + ∫₀ᵗ v(u) du
x(t) = ∫₀ᵗ ((1 ft/s²) u + 1/2 (3 ft/s³) u ²) du
x(t) = 1/2 (1 ft/s²) t ² + 1/6 (3 ft/s³) t ³
→ x (1 s) = 1/2 (1 ft/s²) (1 s)² + 1/6 (3 ft/s³) (1 s)³ = 1 ft
Maggie runs 1/4 of a mile in 1.3 minutes. Olivia runs 2/3 of a mile in 2.9 minutes. Who runs faster? HOW MICH FASTER PER HOUR DOES THE PERSON RUN?
Answer:
Code: Olivia-2.40
Step-by-step explanation:
Given that:
Maggie runs 1/4 of a mile in 1.3 minutes
1/4 can also be written as 0.25
Speed = [tex]\frac{Distance}{Time}[/tex]
Speed = [tex]\frac{0.25}{1.3}[/tex]
Speed of Maggie = 0.19 miles per minute
Speed of Maggie per hour = 0.19*60 = 11.40 miles per hour
Olivia runs 2/3 of a mile in 2.9 minutes
Speed = [tex]\frac{\frac{2}{3}}{2.9}=\frac{2}{2.9*3}[/tex]
Speed = [tex]\frac{2}{8.7}[/tex]
Speed of Olivia = 0.23 miles per minute
Speed of Olivia per hour = 0.23*60 = 13.80 miles per hour
Therefore,
Olivia runs faster.
Difference = 13.80 - 11.40 = 2.40 miles
Hence,
Code: Olivia-2.40
Answer:
Olivia-2.25

Marta's pet snake is 10 inches shorter than three times the length of Dilbert's pet snake. If both their snakes laid together end to end measure 110 inches, how long is Marta's snake? Which equation would NOT solve this problem?

3x - 10 = 110
4x - 10 = 110
x + 3x = 120
Martha needs 7 strawberries for every 1 smoothie.
What are the missing values in the table
Answer:
Strawberries Smoothies
28 4
21 3
70 10
Step-by-step explaination
If Maria uses 28 strawberries you would divide that by 7 (since that's how many she uses for one smoothie) after you divide 28 by 7 you get 4, 4 is the number of smoothies 28 strawberries makes.
If Maria makes 3 smoothies you multiple 3 by 7 (since that's how many strawberries she uses to make one) 7 times 3 is 21. If you want to check your work you would divide 21 by 7 (the number of strawberries used for 1 smoothie) and you would get 3.
If Maria uses 70 strawberries you would divide 70 by 7 (the number of strawberries used for 1 smoothie) 70 divided by 7 is 10, 10 is the number of smoothies 70 strawberries make.
